SPECIFICATION forming part of Letters Patent No. 572,905, dated December8, 1896. Application filed July 18, 1896. Serial No. 599,682. (Nomodel.)

To all whom it may concern.-

Be it known that I, CHARLES L. MCINTIRE, a citizen of the United States,residing at South Norridgewock, in the county of Somerset and State ofMaine, have invented certain new and useful Improvements in Checkrein-Hooks; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. 7

My invention has relation to checkreinhooks for harness, and the objectis to provide a simple and convenient checkrein-hook secured to thesaddle by which the checkrein can be loosened to Water the horse andinstantly secured in place when desired; and to these ends the noveltyconsists in the construction, combination, and arrangement of the same,as will be hereinafter more fully described, and particularly pointedout in the claims.

The figure in the drawing is a perspective View of a checkrein-hookembodying my invention.

A represents the ordinary form of checkrein-hook, the base B of whichforms a plate by means of which the hook is secured to theharness-saddle.

C is a U-shaped spring, one end of which is secured to the hook byrivets c c, the upper or free end being provided with ears D, betweenwhich is j'ournaled a roller E, the pressure of the spring 0 serving tokeep the roller in contact with the inner face of the end of the hook atall times, except when the checkrein is being released or replaced, atwhich time, of course, the roller gives way by the spring action andimmediately flies back into place.

face of the spring, so that should it become necessary to increase ordiminish the tension of the spring this can be instantly done by meansof the thumb-screw drawing the block closer into the bend to increasethe tension and reversing the operation to lessen the tenslon.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, is-

1. As an improved article of manufacture, a' checkrein-hook comprisingthe rigid hook A provided with a U-shaped spring G, the free end ofwhich is provided with ears 1) between which is journaled a roller E, incon1- bination with the block F, and thumb-screw H, substantially as andfor the purpose set forth.

2. As an improved article of manufacture, a checkrein-hook comprisingthe rigid hook A having the U -shaped spring 0, having ears D, betweenwhich is journaled the roller E, in combination with the block F, thecurved face G of which is of a greater circle than the bend in thespring, and adjustable with reference to said bend in the spring bymeans of the thumb-screw H, substantially as and for the purpose setforth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
